	An Earth atmosphere pressurized inflatable habitat has an internal pressure of 5 to 10 tonnes per m2 (50 to 100 kPa). Density of regolith is about 1500 kg/m3, this corresponds to 525 kg of soil pressure per m2 at Mars gravity. So the habitat can support up to 19m of regolith. Studies have shown than a single meter of regolith may be sufficient for radiation protection for both solar storms and [[Cosmic radiation\|GCR]]<nowiki/>s.<ref>Regolth radiation protection- https://eps.utk.edu/faculty/taylor/Miller-radiation%20measurement.pdf</ref>. So an inflatable habitat may well be buried for radiation protection.		An Earth atmosphere pressurized inflatable habitat has an internal pressure of 5 to 10 tonnes per m2 (50 to 100 kPa).

			==Disadvantages==
			*An inflatable may be more prone to catastrophic collapse in case of structural failure, or leaks.
			*An inflatable might be more easily damaged by fire, and materials might be more inherently flammable.
			*Although an inflatable has packing volume advantages, this may not be significant for habitats built on Mars from In-situ resources.
			*Fabrics may be susceptible to fatigue.
